Like its predecessor, it’s going to collect more than eight times more light than a normal kit zoom, which makes it amazing in low-light, produces a shallower depth-of-field for appealing blurred wallpapers, and catches sharper results also.
Meanwhile, the very low cost makes it the most inexpensive lens in Canon’s catalog and the closest you will find to some no-brainer if you have a DSLR or means to accommodate it to some mirrorless body.

Canon EF 50mm Design
In this respect, it is much like this earlier EF 50mm f1.8 II, and really at 69x39mm and weighing 160g, it is practically the exact same dimensions and weight but put them side-by-side plus they seem and feel very different.
Both lenses have plastic cubes, but the brand new EF 50mm f1.8 STM uses a matte finish in contrast to the shinier look of the old version.
The ring on your newest STM variant is wider and works more easily, and you do not need to change to MF to disengage the focusing engine.
The build quality is approximately equivalent, but I am very happy to find the plastic bracket of the old version was replaced with a metal bayonet on the brand new one.
This and all the smoother focusing ring and also brighter finish all give a classier sense to the brand new version.
Bokeh is a phrase used for its out-of-focus regions of a picture and is normally explained in qualitative terms, for example, smooth/creamy/unpleasant, etc… One reason to purchase a quick lens would be to have the ability to isolate the subject from the desktop, and also the Canon EF 50mm f/1.8 STM has an iris diaphragm with 7 curved blades for a satisfying representation of these out-of-focus highlights.
The Canon EF 50mm f/1.8 STM functions nicely with autofocus, marginally less with manual attention.
The AF system is precise and quick, but not the speediest STM motor I have seen.
It functions nicely in low light, as a result of the wide aperture. Rather than the classic ring-type ultrasonic driveway, this lens employs a linear altering mechanism.
This guarantees smoother working with camera bodies that have on-sensor stage detection (Double Pixel AF).
Additionally, it is perfect for autofocusing in movie mode. But, in addition, it suggests the manual focus ring is just joined to the glass.
You want to power on the camera to manually focus. The response of this manual focus ring isn’t linear — the quicker you flip it, the more it changes.
It’s possible to override autofocus in case you turn the ring while the camera is half-pressed.On the lens casing, there’s absolutely not any space scale — that is the privilege of ring-USM-motor lenses. When working, the front part extends from the barrel, but it does not rotate.
Canon EF 50mm Handling and Build Quality
The Canon EF 50mm f/1.8 STM is a really delicate, plastic sole structure with a shiny, cheap-looking outer shell. The STM variant is developed on a metal bracket, and the casing is matte plastic.
It is still not a strength winner, but I do not anticipate any serious problems with this layout. It does not have weather sealing, and also the front part helps to ensure that humidity and water will access the lens should you let it.
Thus, this lens isn’t especially rain-friendly. The filter thread is 49mm, which isn’t a remarkably common filter dimension. Locating filters for this particular size is a very small bit harder compared to 52mm-threaded lenses.
Just like the newly reviewed 40mm, you can not stack filters either. The autofocus motor will have difficulty moving over 1 filter along with the front part.
Canon EF 50mm F1.8 STM Key Features
It needs to be pointed out that having an EF lens, the EF 50mm f/1.8 STM is totally compatible with the Canon full-frame DSLRs and also the ones that use an APS-C detector.
Coupled to this latter as well as the 1.6x multiplication factor of an APS-C camera shot under an account, the EF 50mm f/1.8 STM becomes an extremely functional and creative brief telephoto lens that is equal to 80mm.
To set up the lens’s optical functionality across its entire picture circle, I analyzed it coupled into a Canon EOS 5D Mark III full-frame DSLR, where it delivers a 46° diagonal angle of view.
The same as the two preceding generations of this lens, the EF 50mm f/1.8 STM uses a six-elements-in-five-groups arrangement. The most important difference in its structure is the fact that it currently features seven round diaphragm blades, rather than the five straight blades employed by its predecessor.
This implies it ought to give more attractively-blurred wallpapers at aperture settings smaller than about f/2.5 compared to 50mm f/1.8 II, which provides pentagonal out-of-focus highlights that lots of photographers find quite nasty.
Additionally, it has the capability to concentrate nearer, to 35cm (1.15feet ). The standout feature is that the designation of STM on the front part of the lens denoting it utilizes Canon’s Stepper Motor technologies, which we have seen applied to some range of those producers’ lenses because 2012.
Unlike the more comfortable Ultrasonic Motor (USM), a Stepper Motor is much better in creating the exact incremental moves that are demanded by contrast-detection autofocus in live perspective.
This is great for creating professional-looking focus adjustments when recording video and may also help eliminate any obtrusive operational sounds which may possibly ruin a soundtrack.
Canon EF 50mm F1.8 STM Image Quality
It is the most important part of this Canon EF 50mm F1.8 STM Lens Review.
In the f/1.8, the lens is very sharp, revealing 2,120 lines per picture height onto a center-weighted test.
The outer and middle third display a similar drop-off because they do in f/1.8 and f/2, but nevertheless best at 2,100 lines. In f/4 that the center-weighted score enhances 2,638 lines, and it hastens f/5.6 and f/8, hitting 2,700 lines at apertures.
Diffraction robs a little bit of detail in f/11; the score falls to 2,614 lines.
At no stage do the borders grab with the middle of the framework, but they are not blurry at any given stage, even in f/1.8.
Barrel distortion is a slight problem; the lens reveals 1.2 percentage, which provides straight lines a little outward curve. It is not a huge deal for the majority of photos, but you could notice it sometimes.
Based on the way you take it, the flare may be a problem. I managed to induce it while shooting a wide aperture once the sunlight hit the lens at just the perfect angle.
A hood, that Canon did not supply, is a fantastic investment if you would like to stay away from the result. On the flip side, you might end up seeking it outside for artistic intentions.
From time to time, it’s not difficult to justify purchasing a lens to get a subset of its features (such as cost), but if it’s time to choose the perfect lens for a specific use, the focal length constantly becomes an essential feature.
The focal length determines the angle of perspective which determines the space necessary to your desired subject framing and also the space in the area determines the standpoint.
Luckily with this particular lens, the 50mm focal length comes with a large number of applications.
On a complete frame body, a 50mm focal length seems very natural, approximating the way we perceive a spectacle together with our own eyes’ field of opinion and view stipulations.
In the film days, a 50mm lens has been frequently offered in a 35mm SLR kit, suggesting both this focal length’s fame and its own overall purpose usefulness.
Fifty-millimeter lenses are often utilized in fashion, portraiture, weddings, documentary, lifestyle, sports, design, landscape, and basic studio photography programs such as product photography.
As mentioned, lots of those fantastic applications for this particular lens comprise people as topics.
A 50mm lens applied to a complete frame body is too broad angle for closely framed headshot portraits (A too-close view is needed for my taste at least); however, 50mm is a really good selection for less-tightly-framed shoulders and head, tight body and also full-body portraits.
This flatter angle of perspective is helpful for exactly the very same purposes only cited and tighter-framed portraits keep a much better outlook.
Shooting wide-open in the aperture (f/1.8) leads to strong vignetting in the corners and it is a similar story in f/2 at which you can not fail to observe the dark corners in the borders of the framework.
Stopping down the lens to f/2.8 sees the impact of vignetting reduce appreciably, and although still current it is not quite as evident in real-world pictures.
Putting the lens into f/4 and outside sees the traces of vignetting vanish.
Assessing our laboratory results and sample pictures thoroughly revealed indications of softness at the center in f/1.8. But, stop down to f/2.8 and you will quickly discover that the center instantly begins to sharpen up.
The advantages of pictures are perceptibly soft from f/1.8-f/2.8, however, at the time you stop the lens down to f/4 and f/5.6 corner sharpness improves.
Users that wish to discover the sweet spot and attain supreme sharpness should utilize the lens between f/8 and f/11. Close to the aperture to f/16 and f/22 and diffraction has the effect of burning images.
So the topic “Canon EF 50mm F1.8 STM Lens Review” comes to an end!
If a lens is priced that low, you are prepared to forgive a few of its own shortcomings. The Canon EF 50mm f/1.8 STM is quite sharp, but its autofocus motor is on the side and it reveals a few fall-offs during its widest apertures.
The STM engine is attractive when recording a movie, but too little insertion will present your handheld footage a jittery appearance –particularly when pairing it with a few of the APS-C versions that support Canon’s smooth Live View focus system.
Really, the very fact that lots of a French shot reach the 50mm f/1.8 as a cheap prime could be the most significant barrier in providing it a glowing recommendation.
It is just not as helpful as a general-purpose lens when paired using a scripted as it’s using a full-frame camera.
The EF-S 24mm f/2.8 STM and, even if you want a slightly tighter area of view, the EF 40mm f/2.8 STM, are far better options there, and the two are rather reasonably priced.
